70+ FPE KRAL PB with ART SS valve

[oldpro]

 We finally got the SS valve done and into the Kral puncher breaker and boy were we surprised!!! We went from 45FPE with Two stiff springs to 73 FPE with the stock spring!!! The trigger is now light and crisp also due to the light spring and we shaved off quite a few ounces also and no more broken valve stems either . We had to back the stock spring adjuster almost out of the gun and turn the power adjuster down to get to 50 FPE LOL. We will run strings with a regulator and without shortly stay tuned. 983 with stock spring and 34 grain JSB pellets porting was .190 threw exhaust port to barrel. We didnt even crank it full bore as we were scared it might break the sound barrier and get the law down on us.

"dang"!

I'm all eyes and ears, y'all.

That is very encouraging news!

Any guess what kinda power such a valve would give a Puncher NP-01 in .25?

Seems like 40 fpe would be do-able, if I am guessing correctly..

And that would be one bad-azz upgrade, nice!

[anti-squirrel]

You have my attention.  Puts them back on my radar in a big way!

Nice work Travis, and was wondering when the Kral testing results would get out.
I can't wait to send you my .22 PB for more work + one of the new valves, let me know when this can become a reality, please put me in line for an upgrade as soon as you're ready...

Great, now I've got something else to buy.

[Motorhead]

Lol ... how cool is that ? ............................................ VERY COOL !!!

That's really amazing and not having to beat up the lever, hammer and valve. Please put me on your list for the kral and marauder.

That looks a lot like the valve in Jkhan Noblesse guns. Anybody know are the valve body dimensions the same for Kral/JKhan? And for Evanix too I quess. It's seems to be difficult or impossible to get spare parts for these Hyundai or what ever family of airguns to compare them.

Depends on the caliber and model I'd say, they are all very close but Evanix RS2/Blizzard has a drop style valve block. My .45 Sniper also has bigger valve stem and that nose of the valve housing. It would be very interesting if you guys could identify that the screw on nose in the valve housing can be swapped from Kral to Evanix to JKHan and then make a well flowing nose and valve kits. What are the diameters of the original valve stem vs. the new one, the difference looks huge?

I'm working on the regulated gun now, some fine tuning with the spring was needed.

The original is .195 vs. .125 for the new one.

Noblesse has that drop style block too, so no go. But there should be some market for a good air efficient valve for the Jkhan / Evanix guns as as stock they waste air big time, atleast the bigger calibers. And there are no aftermarket parts available at all.

If someone sends me a Evanix valve of the most common variety I will make up a SS valve,

Gee thanks Travis now I have to buy another Airgun. Can I give my wife your phone number so you can explain why lol.

Travis, I can send you the valve from my Rainstorm II since I have it apart and it's been sitting idle in the safe.
